摘　　要：目的了解厦门地区居民室内氡浓度水平及相关影响因素。方法于2008—2010年选取厦门地区15栋具有代表性的建筑物,采用氡α径迹探测器法测试室内氡浓度,并使用FD-3017RaA测氡仪对所选建筑物周围的土壤氡浓度进行测试。结果厦门地区的室内氡浓度值范围为7～92 Bq/m3,平均值为31.1 Bq/m3。2000年后建成的建筑物室内氡浓度相对较高。室内氡浓度与室外土壤氡浓度具有一定的相关性(r=0.529)。结论厦门地区室内氡浓度值在我国标准范围内,较高的土壤氡浓度会引起室内氡浓度的升高。Objective To konw the indoor radon concentration levels and the influencing factors in Xiamen,China. Methods Fifteen representative buildings were selected and indoor radon concentration was measured by using alpha-track detector and soil radon concentration around the buildings was measured by using FD-3017RaA radon monitor. Results The indoor radon concentration in Xiamen ranged 7 Bq/m3-92 Bq/m3, the average was 31.1 Bq/m3. Indoor radon concentration was higher in the buildings built after 2000. The indoor radon concentration was related to the soil radon concentration and the correlation coefficient was 0.529. Conclusion The indoor radon concentration level in Xiamen is not over the standard limited. Indoor radon concentration will increase with the increase of soil radon concentration.
